Question

what is the authors purpose for including a series of rhetorical questions in passage 2, paragraph 1?
how can activity in one area of the brain prove both love and disgust? how can scientists tell that the person doesnt love the former political candidate and feel disgust at the smartphone?
○ to challenge the reader to think critically about the limitations of scientific research on emotions
○ to express the authors frustration with the complexity of neuroscience
○ to remind her reader that romantic love has not always been around and is a part of human interaction
○ to explain how easily brain activity can be interpreted in multiple ways

Explanation:

The rhetorical questions highlight gaps in how neuroscience can definitively link brain activity to specific emotions, pushing readers to question the limits of such research. The first option directly addresses this by framing the questions as a critical challenge to the limitations of scientific emotion research. The other options are incorrect: the questions do not express frustration, focus on romantic love's history, or explain multiple interpretations of brain activity—they instead critique the ability to make definitive links at all.

Answer:

to challenge the reader to think critically about the limitations of scientific research on emotions
